Experimental aluminum alloy containing 0.8% Ca, 0.5% Zr, Fe and 0.25% Si (wt.%), in the form of a long-length rod 12 mm diameter was manufactured using an electromagnetic casting (EMC) technique. The extremely high cooling rate during solidification (≈104 K/s) caused formation favorable microstructure ingot characterized by small size dendritic cells, fine eutectic particles Ca-containing phases full dissolution Zr Al solid solution. Due to obtained ingots possess manufacturability cold...
The influence of strain rate in the interval (10−5–10−3) 1/s on room temperature tensile behavior, dislocation arrangement, deformation mechanisms, and fracture austenitic stainless steel AISI 316L electrochemically charged with hydrogen was investigated. Independently rate, charging provides increase yield strength specimens due to a solid solution hardening austenite, but it slightly influences behavior steel. Simultaneously, assists surface embrittlement during straining reduces an...
Investigating the effect of Fe and Si is essential for any new Al-based composition, as these impurities can be easily found both after primary production recycling. This study dedicated to filling gap in revealing phase composition an Al-6%Mg-2%Ca-2%Zn alloy combined separate addition Si. was addressed by permanent mold casting solid solution heat treatment. The investigation slowly solidified samples also contributed understanding potential transitions. It that containing 0.5%Fe have...
The results of the research show that it is possible to make axisymmetric blanks satisfying quality and geometrical sizes using process wire feed electron additive manufacturing (3D-printing). Yield strength blank's material achieves 317 MPa, which higher than base cast metal (SS321). It was figured out varying parameters such as rate substrate rotation one may finally obtain printed components various microstructure mechanical characteristics. In other words, can be operated combined in...
The microstructural evolution in welded joint zones obtained both by friction stir welding and ultrasonic– assisted on dispersion hardened 7475 aluminum alloy has been examined together with the analysis of mechanical strength microhardness. It was established that ultrasonic-assisted provided leveled microhardness profiles across weld as well higher compared to those standard welding.
Abstract The effect of electrochemical hydrogen-charging on tensile properties, mechanisms plastic deformation and fracture micromechanisms was studied using two ultrafine-grained (UFG) Cr-Ni austenitic stainless steels. UFG structures with an average subgrain size 200 nm for CrNiMo (316L-type) 520 CrNiTi (321-type) steel were produced hot-to-warm ABC-pressing. Hydrogen-charging up to 100 hours weakly influences stages flow, strength properties elongation the TEM analysis testifies...
Abstract The phase composition, microstructure and mechanical properties of flat-rolled experimental Al-Cu-Mn system alloy with Si Zr additions have been studied. results compared data for the AA2219 commercial pertaining to same alloying system. Hot deformation causes precipitation ~ 100 nm sized dispersoids refinement eutectic particles. yield strength relative elongation hot-deformed are 255 MPa 8.6%, respectively. Subsequent cold reduces by 3.5% increases 50 MPa, while ultimate tensile...
The phase composition, rolling processability and mechanical properties of the experimental Al3Mg2Ca0.8Mn alloy were studied. microstructure as-cast ingots contained aluminum matrix a branched network multiphase eutectics which consisted 4 phases according to our calculations, i.e., (Al), Al6(Mn,Fe), Al4Ca andAl3Mg2. average size eutectic intermetallic particles was approx. 6 mm. Subsequent homogenization annealing caused significant fragmentation spheroidization inclusions, leading...
