MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202617035792 A) filed by Cryostar Sas on March 24, 2026, for A Method For Treating A Workpiece For A Fluid Energy Machine.
Inventor includes Murad-Bickard, Anny.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: The present invention relates to a method for treating a workpiece (100) suitable for a fluid energy machine, especially a shaft (100) for a fluid energy machine, comprising the steps of performing a first heat treatment process on the entire workpiece (100), the first heat treatment process comprising a first solution treatment process at a first predetermined temperature, a first quenching process, and at least one first tempering process at a second predetermined temperature; and performing a second heat treatment process on one or more sections (110) of the workpiece (100), wherein the sum of these sections is smaller than the entire workpiece; the second heat treatment process comprising at least one second tempering process at a fourth predetermined temperature or the second heat treatment process comprising a second solution treatment process at a third predetermined temperature, a second quenching process, and the at least one second tempering process at the fourth predetermined temperature; wherein the first heat treatment process and the second heat treatment process are performed such that an impact toughness in the one or more sections (110) of the workpiece (100) lies within a first predetermined value range and such that a magnetic induction in at least one other second section (120) of the workpiece (100) lies within a second predetermined value range.
