The extent of martensite formation in the steel at given distance from the quench, which can be determined by hardness testing in several areas of a sample, is what hardenability measures. Hardenability also determines the necessary cooling rate, fast or slow, for martensite formation.
1 sie 2013 · The purpose of this work is to improve the surface mechanical properties of L6 and 5140 low alloy steels by two-component surface hardening with boron and copper.
26 lut 2021 · In order to harden even such thin-walled workpieces only on their surface in the range of a few tenths of a millimetre, so-called induction hardening can be used. The principle of induction hardening is based on the induction effect, which is also used in induction cookers or transformers.
Surface hardening, also known as surface heat treatment, includes transformation hardening and shock hardening. Transformation hardening is a heat-treatment process by high-power laser beam irradiation on the surface of metals and other materials.
23 lip 2020 · Surface hardening improves the strength of low-carbon steel without interfering with the toughness of its core. In this study, we focused on the microstructure in the surface layer (0–200 μm) of our low-carbon steel, where we discovered an unexpectedly high level of hardness.
Surface Hardening of Steels: Understanding the Basics is a practical selection guide to help engineers and technicians choose the optimum surface hardening treatment for a given application from an ever increasing number of options.
SURFACE HARDENING, a process that includes a wide variety of techniques (Table 1), is used to improve the wear resistance of parts without affecting the more soft, tough interior of the part.
