Alloy Performance Guide - Rolled Alloys

A nickel base alloy with high chromium and an aluminum addition. Outstanding oxidation resistance to 2200°F, good strength and carburization resistance. 800H/AT N08810 X08811 31 21 45 0.4 Al:0.4, Ti:0.6 High strength austenitic heat resistant alloy for ASME code applications to 1650°F. Oxidation resistant to 1800°F. 446 S44600 Creep of medium and high strength aluminum alloys at Direct data have been obtained for the creep of high- and medium-strength aluminum alloys in the stress range of O.61.2 of the nominal yield strength 0.2 in laboratory air and in aqueous NaCl solution at room temperature. On this basis using known theories approximating functions have been determined for the creep curves. Stress 0.2 serves as a natural boundary for the macroelastic and

High Temperature Alloys - an overview ScienceDirect Topics

High-temperature alloys or superalloys are another challenge. They contain chromium for oxidation resistance and elements like aluminum, vanadium, tantalum, niobium, titanium, zirconium, hafnium, and other elements added as gamma prime formers, which strengthen the matrix of the materials by the precipitation of the gamma prime intermetallic compounds that are stable at high temperatures. High strength Aluminum alloys - AMT Advanced Materials Aluminum Al-MS78 is a very high strength 7000 series Aluminum alloy made via an advanced powder processing route. It shows very high strength and excellent fatigue strength. The strength is about 40% higher compared to A7075. The fatigue ratio is higher than for conventional Aluminum alloys due to the small grain size. It is available up to D=100mm. High temperature steel - IMOA21 rows · Molybdenum has been the key alloying element used to develop creep-resistant ferritic

High-Strength Aluminum P/M Alloys

Although aluminum alloys can attain high strength, the strongest such alloys have often been limited by stress-corrosion cracking (SCC) susceptibility in the highest- strength tempers. For example, the high- strength 7xxx alloys (AI-Zn-Mg and AI-Zn- Mg-Cu) can have severe SCC susceptibility in the highest-strength (T6) tempers. To High-temperature Alloys for Industrial ApplicationsSimilar rare earth additions are used in HAYNES® 230® alloy, a recently developed nickel-chromium-tungsten-molybdenum alloy, that combines excellent high-temperature strength, outstanding resistance to oxidizing environments up to 2100°F (1150°C), premier resistance to nitriding environments, and excellent long-term thermal stability. Improving the Properties of Magnesium Alloys for High elevated temperatures. Increased applications of magnesium alloys for elevated temperature service require the development of low-cost alloys with good creep resistance and sufficiently high strength. The magnesium alloy that has received most attention is AZ91 (Mg-9Al-1Zn, wt.%) which is being used in approximately 90% of all magnesium cast

Microstructures and High-temperature Strength of Silicide

These quaternary alloys exhibit excellent high-temperature strength, although the fracture toughness is still unacceptable for practical applications. Discover the world's research 20+ million members New High Temperature Alloy for Aerospace Applications Feb 05, 2019 · According to an article on ScienceDaily, the new alloy is a titanium carbide (TiC)-reinforced, molybdenum-silicon-boron (Mo-Si-B)-based alloy, or MoSiBTiC, whose high-temperature strength was identified under constant forces in the temperature ranges of 1400°C -1600°C that may be suited for applications including in aircraft jet engines and gas turbines for electric power generation. aluminum 6061 strength vs temperature - aluminum-alloyaluminum 6061 strength vs temperature .
