Aug 09,2019·Often used to harden steels,water quenching from a temperature above the austenitic temperature will result in carbon getting trapped inside the austenitic lath.This leads to the hard and brittle martensitic stage.Austenite refers to iron alloys with a gamma-iron base,and martensite is a hard type of steel crystalline structure.Carbon content-tuned martensite transformation in low May 17,2019·For medium-carbon steel,the -martensite transformation significantly enhances work hardening at the expense of the maximum elongation.For low-carbon steel,however,the Cited by 33Publish Year 2013Author P.Dinesh Babu,G.Buvanashekaran,K.R.BalasubramanianHeat Treatment Processes for Steel IspatGuruThe steel is generally allowed to cool slowly in the furnace,although it can be removed and cooled in some cooling medium.Since the transformation temperatures are affected by the carbon content of the steel,it is obvious that the high carbon steels can be fully annealed at lower temperatures than the low carbon steels.
These medium-carbon steels should usually be either normalized or annealed before hardening,in order to obtain the best mechanical properties after hardening and tempering.Parts made from bar stock are frequently given no treatment prior to hardening,butCited by 5Publish Year 2019Author Y.F.Shen,X.X.Dong,X.T.Song,N.JiaEffect of laser power density on transformation hardening Effect of laser power density on transformation hardening of medium-carbon steel with a fiber laser.71-78.Paper presented at 13th Conference on Laser Materials Processing in Nordic Countries,NOLAMP13,Trondheim,Norway.Effect of Isothermal Transformation Treatment and Depending on the carbon content,the TRIP steels can Effect of Isothermal Transformation Treatment and Tempering on the Microstructure and Hardness of a Medium C and High Si Steels Gülten KAFADAR,1)* Ali KALKANLI,1) Abbas Tamer ÖZDEMR2) and Bilgehan ÖGEL
Nov 09,2012·In this research,a systematic investigation on laser transformation hardening (LTH) process is carried out on high-strength low-alloy medium carbon steel,EN25 using design of experiments (DOE).The effect of input process parameters like laser power,travel speed over the response hardened width (HW),hardened depth (HD),and hardened area (HA) are analyzed.Precipitation Behavior and Mechanical Properties of Ti-Mo Dec 30,2014·Abstract.The precipitation behavior and evolution of mechanical properties of Ti-Mo-bearing microalloyed medium-carbon steel during austenite to bainite transformation were studied,and two different cooling rates including ultrafast cooling (~80 °C/s) and accelerated cooling (~15 °C/s) during transformation were also investigated.STUDY OF THE HARDNESS THE MICROSTRUCTURE OF1050 medium carbon steel.Heat Treatment Processes Such As Annealing,Normalizing,and Hardening is carried on AISI 1050 medium carbon steel after treatment aims to perform hardness testing on the treated and untreated work samples.Full annealing is done at

Transformation hardening,known also as martensitic transformation hardening,is one of most common methods of hardening,which is primarily used for steels (i.e.carbon steels as well as stainless steels).The martensitic transformation is not,however,unique to ironcarbon alloys.It is found in other systems and is characterized,in part
