Effect of Cooling Rate and Deformation on Microstructures

Microstructures and critical phase-transformation temperature of boron-nickel added Nb-treated high strength low alloy (HSLA) H-beams cooled at different cooling rate, with different deformation were investigated. Continuous cooling transformation (CCT) diagram of this new type of steel was obtained by using Gleeble 1500 ther-momechanical

Effect of Trace Boron on Low Temperature Impact Toughness

In this research, trace boron (4ppm, 8ppm, 11ppm) was added into the Nb-added HSLA H-beams. The impact toughness of H-beams with/without boron was examined by Charpy impact test (V-notch). The morphologies of the microstructure and the fracture surfaces of the impact specimens were observed by metalloscope, stereomicroscope and electron probe.

Fracture and Tensile Properties of Boron Added Ni-Base

Tensile and fracture properties of an aged, boron added Ni-base superalloy are investigated in liquid helium and at 7 K. The 200 hour and 923 K aging of this superalloy specimens are performed

Effects of Totally 48 Alloying Elements in Steel (Full

H is the most harmful element in steel, and the solution of hydrogen in steel can cause hydrogen embrittlement and white spots of steel. Aluminum, added into steel as a deoxidizer or alloying element, is much stronger than silicon and manganese in terms of deoxidation. In building welding steel that contains Sb, under austenitic

Introduction to Surface Hardening of Steels

posed on a tough, low-carbon steel core. Of the various diffusion methods (Table 2), gas carburi-zation is the most widely used, followed by gas nitriding and carbonitriding. Case hardness of carburized steels is primar-ily a function of carbon content. When the car-bon content of the steel exceeds approximately
