An author: K.J. Ducki in the paper entitled “Effect of heat treatment
on the structure and creep resistance of austenitic Fe–Ni alloy” on
a page 33 discusses the problem of determining the dependence
between the initial heat treatment of an austenitic Fe–Ni alloy and
its structure, and creep resistance. Specimens of Fe–Ni alloy were
subjected to tests after two variants of heat treatment, i.e. solution
heat treatment followed by typical single-stage ageing, and solution
heat treatment followed by novel two-stage ageing. For the
investigated Fe–Ni alloy after solution heat treatment in the
conditions: 980°C/2h/water, two variants of specimen ageing were
applied for a comparison: single-stage ageing (715°C/16h/air) and
two-stage ageing (720°C/8h + cooling in the furnace up to the
temperature of 650°C + 650°C/8h/air). The thermally treated
specimens were then subjected to a static tensile test at room and
elevated temperatures, and to a creep test in a temperature range
of 650÷750°C, at stresses from 70 to 340 MPa. The study shows a
significant effect of the applied ageing variants on mechanical
properties and creep resistance of the tested austenitic Fe–Ni alloy.
It was found out that both, at the room and elevated temperatures,
the specimens of Fe–Ni alloy after 2-stage ageing were distinguished
by higher strength properties (Y.S, T.S) with a little lower plastic
properties (EL., R.A). As regards extrapolated results of creep tests,
it was found out that at a longer exposure time of ca. 10,000 h,
specimens after single-stage ageing were characterized with
higher creep resistance. Lower creep resistance of the Fe–Ni alloy
after two-stage ageing can be explained by increased brittleness of
the material in boundary areas. The obtained test results may be
used to optimise heat treatment and forecast the operation
conditions of products made out of Fe–Ni alloy at an elevated
temperature.
