    About Microstructural Analysis. Metals and composite materials frequently have specifically engineered microstructures to achieve a desired yield strength, impact strength, hardness, or corrosion resistance. The effect of microstructural and microhardness variations on the formation of hydrogen induced cold cracks (HICC) has been investigated in the multipass weld metals. Multipass weld metal cracking tests were performed with submerged arc welding on 25 mm . The effect of welding, heat-affected zone (HAZ) simulation, and specimen orientation on the microstructure and fatigue properties of Al-Li alloy was studied. HAZ simulation and GTA welding with a filler alloy resulted in a significant change in the microstructure. In the HAZ the primary strengthening phase, T1 (Al2CuLi), in the base alloy in T8 temper was replaced by TB (Al7Cu4Li Cited by: 5. Decomposition of fine-grained austenite ({micro}m grain size) during continuous cooling of an HSLA plate steel (containing C, Mn, Cu, Ni, Cr, and Mo) was evaluated by dilatometric measurements, light microscopy, scanning electron microscopy, transmission electron.
