Machinability Improvement of 17-4PH Stainless Steel by Cryogenic Cooling
17-4PH stainless steel is a martensitic precipitation hardening stainless steel that provides an outstanding combination of high strength, good corrosion resistance, good mechanical properties, good toughness in both base metal and welds, and short time, low-temperature heat treatments that minimize warpage and scaling. This valuable alloy is widely used in the aerospace, nuclear, chemical, pet...

متن کاملInvestigating the microstructure and hardness of 17-4PH steel and Stellite cladded by direct laser deposition process on 17-4PH steel substrate
The purpose of this research is to laser cladding of stellite6 and stainless steel 17-4PH powders on the substrate of stainless steel 17-4PH, and investigate its solidification microstructure. The results showed that the microstructure of the stellite6 cladding has a cobalt solid solution ground phase with an FCC structure and Cr7C3 and Cr23C6 carbides. Also, the values of the primary dendrit...
متن کاملMicrostructural Study of 17-4PH Stainless Steel after Plasma-Transferred Arc Welding
The improvement of the surface qualities and surface hardening of precipitation hardened martensitic stainless steel 17-4PH was achieved by the plasma-transferred arc welding (PTAW) process deposited with Co-based alloy. The microstructure of the heat affected zone (HAZ) and base metal were characterized by optical microscope (OM), scanning electron microscope (SEM) and transmission electron mi...

Dyson's conjecture, already proved by Gunson, Wilson and Good, is given a direct com-binatorial proof. We are going to give a combinatorial proof of [Z). The CCVlStUnt term Of n,&i+jcn (1-XJXj)+ iS This conjecture was proved by Gunson [S], Wilson [IO] and Good [5]. Recently Andrews [l] and MacDonald [7] formulated certain generalizations of conjecture which are still open. Andrews conjectured a...
