Short Introduction:HY-HA 230 /Haynes 230/IMPHY NiCr22W14Mo/AMS 5878/AMS 5891/UNSNO6230/DIN 17744 No 2.4733 is a nickel-chromium-tungsten-molybdenum alloy that combines excellent high-temperature strength and oxidation resistance with very good long-term thermal stability and good fabricability. Establishment of the High Temperature Constitutive The high temperature flow behavior of materials is an important basis to study their formability and to determine reasonable forming process parameters. In this work, the high temperature plane strain compression (HTPSC) tests were employed to reveal the high temperature flow behavior of Haynes 230 Ni-based superalloy under the wide range of temperatures (950°C-1200°C) and strain rates (0.01
Haynes International - HAYNES® 214® alloy Oxidation Resistance HAYNES® 214® alloy provides resistance to oxidation at temperatures of 1750°F (955°C) and above that is virtually unmatched by any other wrought heat-resistant alloy. It can be used for long-term continuous exposure to combustion gases or air at temperatures up to HAYNES 282 ALLOY3 HAYNES ® 282 alloy PRINCIPAL FEATURES Excellent High Temperature Strength HAYNES ® 282 alloy is a new, wrought, gamma-prime strengthened superalloy developed for high temperature structural applications, especially those in aero and land-based gas turbine engines.

Superalloy Welding and Characteristic Defects Successful first part manufacturing of a range of components, such as combustor liners (see Figure 2a), transition ducts (see Figure 2b) and exhaust exit casings, is dependent upon the ability to form fairly complex structures from wrought alloys, such as Nimonic 75, Haynes 230, IN625 and C263.
The results indicate that the number of thermal cycles does not affect the susceptibility of Haynes 230 superalloy to hot cracking. However, it does increase the strain. In weldment of heat treatment, stress relief annealing increases the yield strength and tensile strength of the welded parts.GUIDE TO ETCHING SPECIALTY ALLOYSEtching superalloys in preparation for micro-scopic examination is extremely challenging be-cause of their inherent corrosion resistance. Over the years, Carpenter engineers have developed guidelines for the most effective procedures for etching a wide range of iron-, nickel-, and cobalt-base alloy systems. The following discussion of-
