Expert Solution

Hot press forming (HPF) –also known as press hardening(PHF) It's a sheet metal forming/ manufacturing process used to shape metal parts.

  • a relatively new forming process.
  • Recently developed particularly for the application of a special group of high strength steels in car body manufacturing in the automotive industry.
  • A unique metal forming processing technique.
  • the material is heated up to a sufficiently high temperature to provide austenitic microstructure.
  • then it is cooled down rapidly in the forming tool•at certain cooling rate diffusionless martensitic phase transformation occurs leading to significant increase of the strength parameters.

After additively manufacturing a part, many manufacturers will perform Hot Isostatic Pressing (HIP) to remove pores from the material. These pores form naturally as part of the process of additive manufacturing, and negatively affect the fatigue life and mechanical properties of the part. After HIP, the material often becomes soft since the high temperature of the process also removes the microstructure. What process would you use to strengthen the material after the HIP process without changing shape of the part,...

1) Imagine you are explaining to your friend how Type I and Type II errors work. You friend then asks you, “Why don’t researchers just set the alpha error rate really low (like .01%) every time so the odds they make a Type I error are very small?” Explain to your friend why scientists don’t set the alpha error rate to a very small value every time they do research. Can you think of a reason why a scientist would...
