Research on the Mechanical Characteristics of a Microalloyed Steel with V in the Agreement with Environmental Trends

Abstract

In this paper we studied the behavior of steel 31 VMn12 micronized with V in industrial conditions. In the experiments it was intended to obtain the mechanical characteristics corresponding to the pipe qualities, in the following states of the material: from the heat of rolling; with thermal normalization treatment; with thermal improvement treatment. Experiments have been achieved for two samples made steel and rolled into tubes F 219 x 9 mm.

Experimental Study on the Tribological Behavior of Polymeric Materials Used in Sliding Motion Couples

“…-For the tribological analysis of the behavior under the action of a conical penetrator, the movale specimen will be from relamid and the fixed specimen will be a cone from OL42 which will have the angle at the tip of . The defects of the tapered pins were m 12 /radius [7,8,16]. The samples were loaded in turn with the respective forces N 5 , 0…”
