Title: David Aisman: Innovator in High-Alloy Steel Production

Introduction

David Aisman is a notable inventor based in Plzeň, Czech Republic. He has made significant contributions to the field of metallurgy, particularly in the production of high-alloy steel. With a total of 2 patents, Aisman has developed innovative methods that enhance the properties and production processes of steel.

Latest Patents

Aisman’s latest patents include a method for producing a microstructure of high-alloy steel. This method involves heating the metal stock to a temperature between 1270°C and 1280°C at a rate of 40°C/s to 45°C/s. Following this, compression is applied to the metal stock in a thixotropic process, after which the stock is cooled to ambient temperature. The resulting microstructure features undissolved metal carbides in the form of globular particles of both austenite and martensite microstructures.

Another significant patent is a method for producing pressed sheet parts with integrated preparation of blanks of non-uniform thickness. This process includes heating a steel sheet blank to the austenite region, forming it into a flat semi-finished product, and then deep drawing it into a final shaped part. The method allows for cooling during or immediately after the drawing step, which develops a hardening microstructure, imparting high strength to the final product.
