Title: The Innovations of Bengt Pettersson
Introduction
Bengt Pettersson is a notable inventor based in Trollhattan, Sweden. He has made significant contributions to the field of materials engineering, particularly in the development of advanced alloys for gas turbine applications. With a total of 4 patents to his name, Pettersson's work has had a considerable impact on the industry.
Latest Patents
Among his latest patents is the innovative method for the heat treatment of a nickel base alloy, specifically Alloy 282. This process involves heating the alloy to a temperature between 954°C and 1010°C until the gamma prime (γ') phase is sufficiently dissolved. Following this, the alloy is cooled to a sufficiently low temperature at a high cooling rate to suppress gamma prime precipitation. This method is particularly useful for components such as turbine exhaust cases and gas turbine engines made from this alloy. Another significant patent is for a high durability turbine exhaust case, which features an outer housing secured within a gas turbine engine and a central hub. The design includes struts that extend between the outer housing and the central hub, with the struts formed from a first material and the central hub from a second material.
