Machinability of Steel and Metallurgical Factors

Metallurgical Factors Influencing the Machinability of Inconel 718 John J. Schirra, Pratt & Whitney

Because of the large volume of Inconel 718 used by the aerospace and power generation industries and the high percentage of metal removed to machine complex component geometries; understanding and improving the machining characteristics of Inconel 718 would result in substantial cost savings. While progress has been made in developing improved tool materials and machining processes, a detailed ...

Prediction of steel machinability by genetic programming

Purpose: This paper describes intelligent system to predict steel machinability. Design/methodology/approach: The prediction of machinability of steel, depending on input parameters (percentage of calcium, percentage of oxygen, percentage of sulphur), was performed by means of genetic programming and data on the batches of steel already made. Findings: The mathematical model to predict machinab...

Machinability Improvement of 17-4PH Stainless Steel by Cryogenic Cooling

17-4PH stainless steel is a martensitic precipitation hardening stainless steel that provides an outstanding combination of high strength, good corrosion resistance, good mechanical properties, good toughness in both base metal and welds, and short time, low-temperature heat treatments that minimize warpage and scaling. This valuable alloy is widely used in the aerospace, nuclear, chemical, pet...
