Phase diagrams are graphical representations of the phases present in a particular alloy being held at a particular temperature.  Phase diagrams are used to predict the phase changes that occur in alloys during heating and cooling. This can be during heat treating, casting solidification, joining processes that involve molten metal, and elevated temperature use conditions. This is important because the properties of a metal component depend on the phases present in the metal. In this episode Michael discusses phase diagrams and their use.

Engineering and producing a product or structure involves many decisions and actions, and occasionally mistakes are made. Sometimes they are easy to fix and not costly. Other times the mistakes take a great deal of effort and money to fix. Regardless, the general categories of mistakes can be put into two categories – mistakes due to process or procedure errors and mistakes due to ignorance.   in this episode Michael discusses these types of mistakes, their causes, and ways to prevent them from occurring.

In this episode, Michael discusses different aspects of product development, product launch, and post-launch where materials engineering will improve product success.Developing and launching a product can be stressful – there are many decisions, problems to overcome, and risks to mitigate. While we’d like the process to go smoothly and be able to calmly meet deadlines, this usually is not the case – things we didn’t consider pop up or things that shouldn’t have been a problem become a problem. Many of the decisions, problems, and risks are associated with the materials used in a product. After all, a product is ultimately an assembly of materials that have been shaped, manipulated, and modified. So, making the effort to engineer the materials will have an impact on product cost, performance, and reliability,and on manufacturing throughput and quality.To learn more about successful product development, launch, and improvement check these out-https://youtu.be/D_rtl7TNrQE-https://www.imetllc.com/product-launch-formula/This episode is a complement to articles and podcasts available on the ⁠⁠⁠⁠⁠Industrial Metallurgists website⁠⁠⁠⁠⁠ https://www.imetllc.com/.---------------------------Michael Pfeifer, Ph.D., PE is a metallurgist and metals engineer.
