Superadiabatic combustion with reciprocating flow in a porous medium has been investigated through numerical calculations.

Special designed drive outfit and PLC are adopted to control object moving to-and-fro and rotating at prearranged positions.

Structure refinement and mechanical properties of Mg-4Al-2Si Mg alloy by reciprocating extrusion;

Microstructure and ageing behavior of Mg_2Si/Mg-Al composites produced by reciprocating extrusion;

Microstructure of bulk Mg_(92.5)Zn_(6.4)Y_(1.1) magnesium alloy prepared by reciprocating extrusion from rapidly solidified ribbons;

6%Zr were prepared by a combination of processes of rapid solidification (RS), reciprocating extrusion (RE) and extrusion (EX).

In order to solve the problem of low yield of spindle yarn on the winding machine,analysis finds out the main cause is due to the unstable quality of the key element,the reciprocate screw.

1 magnesium alloys were prepared by reciprocating extrusion(RE) and forward extrusion processes.

The tribological properties under reciprocating sliding condition of two TiAlN coatings, prepared by magnetic sputtering, had been tested on a PLINT wear tester.

To examine the tribological behaviors of TiAlN coating which deposited on the surface of wimet substrate,the reciprocating sliding tests were carried out under different media(in air,in emulsion and in coolant oil) and different parameters(normal loads and displacement amplitudes).

Different behaviours of unidirectional(ball-on-disc)and reciprocating sliding wear were investigated under the conditions of the same number of cycles.
