Effect of cathodic potential on stress corrosion cracking behavior of different heat-affected zone microstructures of E690 steel in artificial seawater

, 2019
In this work, the stress corrosion cracking (SCC) behavior of E690 steel base metal (BM) and different heat-affected zone (HAZ) microstructures, i.e., coarse grain HAZ (CGHAZ), fine grain HAZ (FGHAZ), and intercritical HAZ (ICHAZ), was investigated at ...

Improved toughness of double-pass welding heat affected zone by fine Ti–Ca oxide inclusions for high-strength low-alloy steel

, 2020
In order to improve the mechanical performance of double-pass welding heat affected zone, acicular ferrite (AF) induced by Ti–Ca oxide inclusions was used to enhance the toughness properties of the intercritically reheated coarse-grained heat-affected ...

Fatigue crack propagation through weld heat affected zones

Metallurgical Transactions, 1971
Fatigue tests were performed on specimens containing weld heat affected zones at two orientations to the stress axis. Two heat affected zones were studied, one in Ducol W30 (a low alloy steel) and the other in mild steel. Under conditions of constant alternating and maximum stress intensity a fatigue crack only propagated at a uniform rate when it was ...

Heat Affected Zone in Grinding Operations

1974
The temperature rise, due to the passage of a grinding wheel, may have detrimental effects on the surface integrity of the outermost layers of the ground workpiece. In this contribution, a comparison has been made of various models, worked out for evaluating the heat affected zone.

Small Punch test for weld heat affected zones

Materials at High Temperatures, 2006
AbstractSmall Punch tests (SPT) have been performed on four different zones of P91 welded joint, namely the base metal (BM), the weld metal (WM), the heat affected zone at base metal side (HAZ-BM) and the heat affected zone at weld metal side (HAZ-WM).

Temperature-gradient induced microstructure evolution in heat-affected zone of electron beam welded Ti-6Al-4V titanium alloy

Journal of Materials Science & Technology, 2019
The heat-affected zone (HAZ) of electron beam welded (EBW) joint normally undergoes a unique heat-treating process consisting of rapid temperature rising and dropping stages, resulting in temperature-gradient in HAZ as a function of the distance to ...

Heat affected zone cracking in cast inconel 718

Materials Characterization, 1992
Abstract Electron beam welding parameters have been shown to influence heat-affected zone (HAZ) microfissuring behavior in cast Inconel 718 (Inconel is a trademark of INCO Alloys). Travel speed was shown to be the most significant factor in influencing HAZ cracking behavior by modifying the thermal gradient(s) and subsequently the stress state in the

Heat Affected Zone in the MEMS Wire Bonding

2009 International Conference on Measuring Technology and Mechatronics Automation, 2009
In the wire bonding process of MEMS packaging, Heat Affect Zone (HAZ) is the important factor governing the loop profile of bonding. The height of loop is affected by the length of the HAZ. Factors governing the HAZ are studied. To investigate this relationship, the experiments were done for the various sizes of wire diameter and Free Air Ball (FAB ...
