  • Component Distortion An Overview
  • Year: 2018, Source: The Shot Peener magazine, Vol 32, Issue 2, Spring 2018
  • INTRODUCTION: Every shot peener distorts components—if only in the form of Almen strips. They would be useless if they didn’t distort! Distortion is caused by a combination of plastic deformati...

  • Decarburization: The Silent Enemy
  • Year: 2018, Source: The Shot Peener magazine, Vol 32, Issue 1, Winter 2018
  • INTRODUCTION: A large proportion of metallic engineering components are made from carbon steels. These components may encounter high temperatures during furnace heat treatment and/or hot working...

  • Variations on the Almen Technique
  • Year: 2017, Source: The Shot Peener magazine, Vol 31, Issue 4, Fall 2017
  • INTRODUCTION: First instigated in 1942 with a patent submission, the Almen technique has now provided a reliable and universally accepted method of measuring peening intensity based on the defle...

  • Work-Hardening During Peening
  • Year: 2017, Source: The Shot Peener magazine, Vol 31, Issue 3, Summer 2017
  • INTRODUCTION Shot peening is normally applied in order to improve the fatigue properties of components. This improvement is due to two factors: (1) Work-hardening of the surface layer and (2) Compr...

  • The Importance of Work
  • Year: 2017, Source: The Shot Peener magazine, Vol 31, Issue 2, Spring 2017
  • INTRODUCTION: Work and rate of doing work are, arguably, the most important parameters in the Universe. No event can happen unless some work is done at a measurable rate. Even blinking an eye require...

  • Coverage Variability
  • Year: 2017, Source: The Shot Peener magazine, Vol 31, Issue 1, Winter 2017
  • INTRODUCTION Coverage is one of the most important parameters in shot peening. It is specified in J2277 to be the “Percentage of a surface that has been impacted at least once by the peening med...

  • Shot Stream Generation
  • Year: 2016, Source: The Shot Peener magazine, Vol 30, Issue 4, Fall 2016
  • Introduction: Air-blast shot streams consist of a mixture of fast-flowing air and entrained shot particles carried along by the flow of air. Generating an air-blast shot stream embraces two main prob...

  • Peening Intensity True Meaning and Measurement Strategy
  • Year: 2016, Source: The Shot Peener magazine, Vol 30, Issue 3, Summer 2016
  • INTRODUCTION The two most important quantitative terms for shot peeners are “Coverage” and “Peening Intensity.” “Coverage” has a single, unambiguous, definition: The percentage of the p...

  • Optimization of Shot Peening Coverage
  • Year: 2016, Source: The Shot Peener magazine, Vol 30, Issue 2, Spring 2016
  • INTRODUCTION Shot peening coverage of components is, of course, very important. The importance of coverage optimization is emphasized in SAE J2277 with its: “Effectiveness of shot peening is dire...

  • Wear and Its Reduction
  • Year: 2016, Source: The Shot Peener magazine, Vol 30, Issue 1, Winter 2016
  • Shot peeners are beset with wear problems. Every piece of shot and all peening equipment are subject to wear to a greater or lesser extent. A universal example is the wear endured by shot particles on...

  • Verification of Peening Intensity
  • Year: 2015, Source: The Shot Peener magazine, Vol 29, Issue 4, Fall 2015
  • Verification of peening intensity is described in SAE J443 using just the three paragraphs of section 3.5. This article attempts to provide a much fuller explanation of the basic issues involved when ...

  • Principles of Peening Intensity Selection
  • Year: 2015, Source: The Shot Peener magazine, Vol 29, Issue 3, Summer 2015
  • The most difficult shot peening question to answer is, probably, “What peening intensity should I apply to my component?” For any specific component, an answer should be based on a combination of ...

  • Essential Elements of Shot Peening
  • Year: 2015, Source: The Shot Peener magazine, Vol 29, Issue 2, Spring 2015
  • Shot peening is a very important metalworking process–mainly used to substantially improve the fatigue life of components. There is now such a wealth of information about the process that often one ...

  • Quantification of Shot Peening Intensity Rating
  • Year: 2015, Source: The Shot Peener magazine, Vol 29, Issue 1, Winter 2015
  • This article is complementary to the previous TSP article– “Quantification of Shot Peening Coverage.” As such, it considers the second of the two most important shot peening requirements spec...

David Kirk

Born into a multi-generational steelworking family — his grandfather was a Head Roller and his father was an Open-Hearth steelmaker and also a part-time lecturer at Rotherham Technical College — David won a scholarship to a local grammar school. Grammar school success secured three scholarships that took him to Birmingham University to read Industrial Metallurgy. He was the first member of his family to attend university. After graduation, a Department of Science scholarship allowed research that finished with a doctorate for a thesis entitled "The Hot Working of Metals."

First employment as a Research Fellow at Birmingham University was followed by a short period as a Senior Research Metallurgist at the International Nickel Company's Research Laboratory in Birmingham. David then joined Coventry University as a Senior Lecturer in Metallurgy. At Coventry University, he was promoted to Principal Lecturer in Metallurgy and then Chairman of the School of Materials. Initial research activity centered on X-ray residual stress measurement which prompted him to establish Coventry Science Consultants Ltd. This was followed by his installation of a shot-peening research laboratory at the University with active encouragement and advice by the late Jack Plaster.

Upon retirement, David was first appointed as a Visiting Research Fellow and is now Visiting Professor of Materials at Coventry University. David has, after retirement, published some 70 research papers and articles on shot peening and residual stresses. Following his organization of the International Conference on Shot Peening in Oxford, he was elected Chairman of the International Scientific Committee for Shot Peening and he was subsequently elected to be a Life member. David was awarded The Shot Peener of the Year award in 2001 for his significant contributions to the advancement of shot peening.
