Differential thermal analysis of nickel superalloy 718Plus

Popis výsledku v původním jazyce

Alloy 718Plus is one of newly developed nickel super-alloys following the world most widely used nickel super-alloy IN718. Alloy 718Plus was developed by the Allvac company in USA. Principal requirements for the alloy design were increasing the temperature capability by 55 °C higher than that of alloy 718, up to 700 °C, and conservation of comparable processing characteristics (workability and weld ability) and economical characteristics (low cost of raw materials and production process) as the alloy 718. This paper deals with the investment casting of the alloy 718Plus. In this work the technique of Differential Thermal Analysis (DTA) was selected for the study of 718Plus. Particular attention was paid to determination of the phase transformation temperatures (liquidus, MC carbide formation temperature, ?´ and ?´´ precipitation temperature, etc.) and to the effect of varying heating/cooling rate on these temperatures.
