Oxygen affects the microstructure and the mechanical properties of titanium alloys.
Ti-6Al-7Nb is a promising alloy to use in PM due to its outstanding biocompatibility and mechanical properties required for load bearing medical implants.
The presence of oxygen causes high costs in the PM industry, affecting the mechanical behaviour of titanium alloys as it can significantly decrease its ductility [3,4].
There are some investigations about the microstructural factors influencing the fatigue properties.
Summary In the present work, the influence of oxygen on the mechanical properties of Ti-6Al-7Nb processed by MIM was investigated and evaluated

A number of factors considered important in controlling the properties of steel products and affecting the residual manganese in the basic Oxygen furnace (BOF) have been investigated by changing some industrial parameters, aiming at optimizing the residual manganese in BOF.
The studied factors were manganese oxide in the slag, iron oxide in the slag, tapping temperature, Slag basicity, Lance height, blowing time, and carbon content.
In order to study the behavior of manganese oxidation, the factors affecting the residual manganese were studied at the end of the blow.
The parameters affecting on the residual manganese during steel making process in basic oxygen furnace BOF was investigated, 2.

To improve the mechanical properties of composite materials, we could modify both the matric and the fiber sides.
Three factors that directly affect the value of mechanical properties are the degree of cure temperature, cure time, and type of resin [1].
The vinyl ester resin has various mechanical properties, it is depending on the post-curing temperature.
Post-curing above 100 °C causes an increase in adhesion due to the complete cross-linking of Vinyl Ester resin in the joint and the increase in its mechanical properties [4].

The adhesion between the carbon fibre reinforced copper matrix composite material and the coating is of particular importance for the mechanical and functional properties of the resulting system, and also for its handling and for the lifetime of the final product.
Both, processes and materials affect interface properties and - in some cases - the microstructure of the base material near the interface.
During the process flow, the materials are exposed to the action of various external factors, mechanical, thermal, or electrochemical [4].
Frequently, one factor is dominating among other factors affecting theageing of the materials and the degradation and eventually the failure of the part of product.

Since the spot welding process was completed in a very short time and there were many factors affecting the generation of welding defects, it was difficult to control all experimental factors of welding.
Table 1 is chemical compositions and mechanical properties were also used in this experiment.

This management issue will introduce some uncontrollable factors and difficult to tracing.
A proposed quality factor defined as the ratio of the tensile strength of weld to the tensile strength of the base metal was applied for the Taguchi analysis in order to obtain the optimized combination of the control factors for laser welding.
That means the mechanical properties of the weld is already higher than that of base metal.
Since the SNR is dramatically affected by the property variation of the base metals, a strictly income material control was advised to improve the uniformity of weldment.
(3) To deal with the larger property variation of base metal, the proposed quality factor R is better than the tensile strength of the weldment in Taguchi analysis.
