Influence of Processing Conditions on the Mechanical Properties of 17-4PH Specimens Produced by Additive Manufacturing

The purpose of this research is to study the influence processing conditions that affect final behaviour specimens made from a 17-4PH composition powder without necessary thermal treatment be considered 17-4PH, which manufactured using additive technique known as plasma metal deposition (PMD). To end, two walls prealloyed were built under distinct atmospheric conditions, i.e., air and argon, with previously optimized manufacturing parameters. additional effect applied treatments (TT) was studied by means property microstructural analyses extracted each consolidated wall. consisted heating rate 10 °C/min 482 °C (TT1) 620 (TT2), temperatures for 1 4 h, respectively; cooling 5 both treatments. According findings, presence an argon atmosphere during promoted austenite phase, reducing deformation samples enhancing their Young’s modulus. TT1 positively contributed, improving mechanical properties in general, TT2 substantially improved elongation sets specimens.
