High-voltage Lorentz electron microscopy studies of domain structures and magnetization processes in pearlitic steels
TL;DR: In this article, it was shown that the microstructural parameters that affect the coercivity most strongly are the volume fractions and grain sizes of ferrite and pearlite, and a simple model was derived from these observations, which correctly predicts the coercivities of a large number of steels.

Similar and dissimilar resistance spot welding of advanced high strength steels: welding and heat treatment procedures, structure and mechanical properties
TL;DR: In this paper, the microstructure and mechanical properties of spot welds were evaluated using metallographic technique, microhardness and tensile shear tests, and the results showed that the tendency to fail in the pullout mode increased in the order of DP/DP, TRIP/TRIP and DP-TRIP welds, which was caused by the different hardness distribution, carbon equivalent and susceptibility to shrinkage void formation of spot weldings for different combinations.

Fatigue behaviour of laser welds of high-strength low-alloy steels
J. Oñoro,C. Ranninger +1 more
TL;DR: In this paper, the performance of laser-welded high-strength low-alloy (HSLA) steels has been evaluated under the present test conditions of 260 MPa and showed that cracks usually start in the fusion zone, near to the borderline between the fusion and heat-affected zones, the cracks growing right into the base metal by the transcrystalline cracking process.

Phase quantification in low carbon Nb-Mo bearing steel by electron backscatter diffraction technique coupled with kernel average misorientation
Yu-Wen Chen,Yu-Ting Tsai,Po-Yen Tung,Shao-Pu Tsai,Chih-Yuan Chen,Shing-Hao Wang,Jer-Ren Yang +6 more
TL;DR: In this article, an efficient and accurate method is developed for microstructural quantification of complex phases in a low carbon Nb-Mo bearing steel, of which optical micrographs show that it consists of granular bainite and a small amount of ferrite.

Induction-assisted laser beam welding of a thermomechanically rolled HSLA S500MC steel: A microstructure and residual stress assessment
R. S. Coelho,R. S. Coelho,M. Corpas,J.A. Moreto,A. Jahn,J. Standfuß,A. Kaysser-Pyzalla,A. Kaysser-Pyzalla,Haroldo Cavalcanti Pinto,Haroldo Cavalcanti Pinto +9 more
TL;DR: In this article, the effect of different combinations of induction heating and autogenous CO2 laser welding on the gradients of microstructure, microhardness and residual stresses in butt-joints of thermomechanically processed S500MC steel grade was investigated.
