Abstract:

At the present level of alloying, the alloy A has a high reistance and is extensively used in industry for short-term service, of the order of 100-300 hr. The high heat resstance of the alloy t a comparatively econoic alloying is of interest from the point of view of its utilization for longer service perios than that which occurs in aviation. Alloy B is a modification of alloy A. The present article cites the results of testing specimens of these alloys made by the precision casting method, and also specimens from alloy B cast in sand molds. As a result of the stress-rupture tests it was concluded that alloy B has higher values of stress-rupture strength than alloy at 800 degrees. A change in the casting method of alloy A preciion casting and sand-mold casting does not have any substantial effect on the stress-rupure strength. Author
