Its properties stem from a fine-grained microstructure afforded by the low carbon content, microalloying and thermo-mechanical processing used in its production.
Although HSLA-65 has high weldability, the heat input associated with welding can be detrimental to its mechanical properties.
These factors can help diminish welding induced distortion, degradation of mechanical properties in the HAZ and fabrication costs.
Further testing is required to fully develop an understanding of the mechanical properties of the weld metal and HAZ.

Current studies at home and abroad are mainly focusing on aspects of its structural design, kinematics, dynamics analysis, except mechanical efficiency.
In this paper, combining kinematics and dynamics, some factors affecting the Friction Power Loss of a rotary engine are studied and discussed. 2 Introduction of the new rotary engine Object of this study is a new rotary engine, as shown in Fig 1, and the basic principles of the rotary engine, as described below.
Considering that, the rough surface of piston ring-cylinder liner would affect the lubrication properties of the piston ring, this paper adopts the average two-dimensional Reynolds equation [4,5]:
(7) Piston speed is represented by; lubricant viscosity is represented by; shear flow factor is represented by [5]; the time is represented by; nominal film thickness is represented by ; the pressure flow factor is represented by,[4]; represents a dimensionless factor; Integrated surface roughness is represented by,,and are RMS of cylinder liner and piston rings surface roughness. 3.4 The asperity contact model.
During the gas explosion and doing work, the film thickness reaches the minimum and the film pressure reaches the maximum, it’s due to many factors , such as the rising temperature and pressure generated by the gas explosion, the falling viscosity of lubricating oil and the decreasing piston velocity.

The model can be employed as a guideline to design cooling approach to achieve desired microstructure and mechanical properties such as hardness.
Once the temperature history is known the important mechanical properties of the low carbon steel bar can be obtained such as hardness and strength.
Then important mechanical properties such as hardness can be computed.
This means that the mechanical properties such as hardness will be different.

The friction results can be reproduced using a friction factor of m= 0.85 at 300 °C and m= 0.7 at 400 °C.
Additionally, the complex stick-slip effect or intermittent contact behavior takes place in the bearing channel, affecting strongly the final velocity distribution and the product surface.
However, the superficial conditions such as asperity, oxidation layer and hardness also affect this complex phenomenon [7].
If a sticking condition is considered, the friction factor m=1 is assumed.
