Method for avoiding inclusions in powder high-temperature alloy disc

The invention relates to a method for avoiding inclusions in a powder high-temperature alloy disc, which comprises the following steps of: carrying out mass point tracking on the inclusions in the processes of cutting a bar into sections, processing and carrying out isothermal forging forming on the disc by adopting numerical simulation so as to judge the positions of the inclusions in the disc, and judging whether the inclusions in the disc are on a part or not based on a disc forging drawing and a part drawing; if the inclusion exists on the part, whether the size of the inclusion in the disc on the flaw detection surface exceeds the acceptance standard requirement or not is judged according to the accumulated deformation of the inclusion and the quantitative relational expression of the size of the inclusion and the deformation, if not, the bar cutting and the subsequent disc preparation process can be executed, and if yes, the machining process is completed. And if not, the bar cutting blanking drawing ne
