  for aircraft forgings and other critical components. The rapid-solidification process is the basis for these new alloy systems, called wrought P/M alloys. The term wrought P/M is used to distinguish this technology from conventional press-and-sinter P/M technology. Grades 7090 and 7091 are the first...

These results are. compared with the results obtained after a. conventional SP surface treatment. Mitigation of SCC & Corrosion Fatigue Failures...
• Durable Catalytic Converter Mounting with Protective and Support Seals (.pdf)
  Advanced substrate design, efficient washcoat/catalyst formulation and robust packaging are critical elements to assure performance and durability of catalytic converters and diesal particulate filters. Radial seals, axial seals and L-seals made of. knitted wiremesh are used with conventional...
• Performance Characteristics of a Newly Developed Cost-Effective Cr-Ni Prealloyed Steel Designed to replace Fe-Ni Steels
  and excellent properties, but require careful sintering and heat treatment. The purpose of this paper will be to demonstrate the properties achievable with a new prealloyed Cr-Ni steel (Astaloy CMN) that is suitable for sintering in endogas and for conventional atmosphere heat treatment. The heat treated...

These. include the noticeable reduction of grain growth, decarburization and oxidation of the pin/main. surface. The hardened zone is clearly defined and "crisp" (Figure 4) without...
• Steels for Strength
  and machined in the solution-annealed condition but not without difficulty. Weldability is excellent. They can be heat treated to 250 to 300-ksi yield strength with a simple 900 F aging treatment. Fracture toughness of the maraging steels is considerably higher than that of the conventional high-strength...
• Let The Chips Fly
  Copper-rich alternatives to conventional AISI austenitic stainless steels sport similar mechanical and corrosion properties but are much easier to machine. Ugine Stainless & Alloys Inc. Regulator-adjustment screw made from 304Cu stainless steel is used in the soda industry to regulate soda pressure...
