Introduction Tribology is the science that studies the behaviour of the surfaces that are subjected to load, in contact and relative movement, so the phenomena of friction, wear and lubrication are topics of this science [1, 2].
Surface fatigue is a process by which the surface of a material is weakened by cyclic loading, which is one type of general material fatigue.
Some works have been done in order to study the RCF wear in different materials [6-10].

As shown in Fig.4, 170P1 and DX54D + Z material comprises uniform ferrite.
More uniform and fine ferrite. it not only has high strength and hardness, but also has a certain toughness, so the hardness is higher than the weld heat affected zone and the hardness of the base material.

Introduction Composite materials, due to their high strength/weight ratio, have been extensively used not only in aerospace industry but also in marine and automotive industries.
In some of the applications, the composite materials may be subjected to high strain rate loading, and thus investigating the high strain rate responses is becoming an essential task.

A larger m implies a more homogeneous material.
It is also demonstrated in Zhu et al. [13] that the failure patterns depend on the mechanical properties of the cushion materials.
