The comparative analysis of operation
characteristics of cold heading female moulds, produced
from steels P6M5 and X12M, in relation with their
structure and stressed state, is carried out.

In the article there is examined the influence of
loading speed, and also of the dynamic parameters of the
hydraulic testing presser and inflexibility of the test sample
on the results of statistic examinations of road fitment on
compression.

There is given the solution of linked problem of
heat conduction and thermoelasticity at heating of
prismatic substances by radiant convection current,
based on using of the method of equivalent sources.

The article is dedicated to the examination of a raw
of matters, concerned with the determination of essence
and estimation of structure parameters of production plants
as factors of their innovation activity. There is determined
the essence of structure characteristics from the viewpoint
of system approach, shown their role in forming of the
enterprise potential, determined the connection with the
complex of aims of the latter. The results of the carried out
by authors investigation of influence of structure parameters
on the level of innovation activity of the enterprises of
metallurgical and foundry sub-branch of RB are briefly characterized.
