Paper presents the results of studies on primary crystallization and wear resistance of high chromium cast iron inoculated with

ferrotitanium intended for work in abrasive conditions. Primary crystallization was examined with use of TDA method, wear tests of the

samples were conducted using the modified pin-on-disk method.

The article shows results of studies of primary crystallization and wear resistance of Cr-Ni-Mo cast steel intended for work in corrosive

and abrasive conditions. The studies of primary crystallization were conducted with use of TDA method and modified tester allowing

measurement casting cooling time influence on the cooling and crystallization curves of studied alloys. After heat treatment of examined

cast steel wear tests of the samples were conducted on pin-on-disc type device.

In this paper crystallization studies of low-alloyed construction cast steel were presented for different additions of chromium, nickel and

molybdenum modified with vanadium and titanium. Studies were conducted using developed TDA stand, which additionally enabled

evaluation of cooling rate influence on crystallization process of investigated alloys.
