Metals Engineering and Product Reliability

In the previous article I discussed product design in general and the importance of leveraging materials engineering to design components that meet performance and reliability requirements at low cost. Both component form and materials can and should be engineered to optimize a component’s design.

In this article I discuss a component design process that explicitly includes materials engineering considerations. This process involves consideration of all design requirements and cost. Not just designing for reliability. That’s where selecting materials gets tricky – having to consider different sets of requirements and design for ease of component fabrication and joining.

This article is the first in a series about material engineering and product reliability. The intent of the article is to provide you with a basic understanding of product reliability as viewed through the eyes of a material engineer. When I first talk to engineers who have a different background or focus, I start with the basics. As we speak more, I expand into relevant areas one at a time. That is what I hope to do with this series. Introduce you to some basics, and then move on to a deeper dive into the topic.

When considering product reliability, a materials engineer is concerned with how the materials in components respond when exposed to stressors that can cause the materials to degrade. Stressors include mechanical loads, corrosive environments, chemicals, heat and cold, electricity, and radiation. You may find additional stressors based on the environment components are used in, or how they are used. It’s a problem if a component or joint in a product degrades to the point where it stops functioning as required.
