  • Publication number: 20230120906
    Abstract: A high-strength and high-plasticity TWIP steel and a preparation method thereof are disclosed. In the disclosure, comprehensive properties of TWIP steel are improved by inclusion modification with Ce and Ba addition, fine grain strengthening and twinning nanocrystallization; the grain size is controlled by a low-temperature cold rolling, a transient annealing treatment and a low-temperature tempering treatment. Considering the addition of Ce, stacking fault energy of the TWIP steel is reduced, and the formation of twins, and the division of twins into grains are promoted, which further reduces a mean free path of dislocation motion, thereby improving yield strength, and finally obtaining a high-strength and high-plasticity TWIP steel.

  • Publication number: 20230056508
    Abstract: A method of machining includes mounting a component in a drilling machine. The component has a target region where the hole is to be drilled. The component and a jet head are situated relative to each other in a drilling arrangement in which the target region is at a first position that is vertically equal to or vertically above a second position at which the jet head is located. A liquid stream is jetted from the jet head and contains either abrasive particles or a laser beam. The stream impinges the target region, and the abrasive particles or the laser beam cause removal of material from the component to form the hole. The liquid stream rebounds off of the component as back-splash. The drilling arrangement causes gravitational draining of the back-splash from the target region to reduce interference between the back-splash and the liquid stream.
