Abstract Scope |
Solid nanoparticles present in a metal can become an obstacle to the movement of dislocations.
To obtain the alloys under study, 0.5 wt% of tungsten nanoparticles with mechanical stirring. The alloys were obtained by casting in a steel chill mold with vibration treatment until complete solidification.
Tensile tests were carried out on an Instron 3369 machine with a moving crosshead speed of 0.2 mm / min.
It was found that for an alloy with tungsten nanoparticles, the values of the yield stress increase from 52.5 to 79.4 MPa, the ultimate tensile strength from 140 to 155.4 MPa, and the values of maximum deformations from 1.9 to 5.5%.
