MECHANICAL AND PHYSICAL PROPERTIES OF THREE SUPERALLOYS, MAR-M200, MAR-M302, AND MAR-M322,
Abstract
This memorandum deals with the mechanical and physical properties of three superalloys for elevated-temperature service. One of these, MAR-M200, is a nickel-base alloy and the other two, MAR-M302 and MAR-M322, are cobaltbase alloys. A request for data was made to several laboratories known to have tested experimental lots of the three alloys. The first section (Chemical Compositions and Physical Properties) contains general information on all three alloys. The second section (Data Curves) contains plots of the raw mechanical- and physical-property data. The third section contains the raw-data sheets as obtained from the contributors. The MAR-M200 alloy was designed for severe operating conditions primarily as blades and vanes in gas-turbine applications. The MAR-M302 alloy was designed primarily for use as a first-stage nozzle guidevane material in advanced engines. The MAR-M322 alloy may find use as turbine-blade material as well as a guidevane alloy because of its increased strength. (Author)
