Titanium is seen as a good material for application in many fields due to its compatibility with different environments. However, it remains unclear whether what happens when this material is exposed to certain high temperatures for longer periods of time. The primary objective of this study was to investigate the effect of heat on a 3 mm commercially pure titanium grade 2 plate at a constant temperature of 900°C at different heating times. Three different heating times were employed in this study: 30 minutes for the first period, 60 minutes for the second period, and 90 minutes for the third period. All heated samples were air cooled to room temperature after each heating period. Microhardness, microstructure, tensile strength, and scanning electron microscopy (SEM) tests were performed. All the results were analyzed and compared with the parent sample. It was observed that the heating period influenced microstructural arrangement of the material. The microstructural changes affected negatively the ultimate tensile strength while percentage elongation was improved. The microhardness of the heat treated samples were firstly negatively affected which later jumped and exceeded that of the parent material.

“…The interest in the use of aluminum alloys is based on appealing characteristics like high strength to weight ratio, appearance, higher ductility, and ease of fabrication [4], [5]- [7]. Various aluminum alloys behave differently due to the different alloying elements used to produce them [8] - [10]. However, it is a well-known fact that material improvements are very essential for better performance as well as for increasing the life span of components [11].…”

“…Friction stir processing (FSP) "is an emerging microstructural modifying technique that uses similar principle as friction stir welding (FSW) to process materials in various ways besides joining them [8], [13], [15], [16]. The two techniques use similar parameters but working with different surfaces, i.e., FSW works on two base metals while FSP operates on a single surface.…”

Friction stir processing (FSP) is a microstructural modifying technique that uses the same principles as the friction stir welding technique. FSP technique can be employed on the same surface repeatedly as desiredand this repetition is called multi-pass friction stir processing (MFSP). The recent developments have shown that MFSP technique is very useful towards uniform dispersion of reinforcement particles during fabrication of surface composites. Some studies have also demonstrated that MFSP technique can be employed on welded joints as a way of improving the mechanical properties of the welded joints. This paper reports on the progress made in using the multi-pass friction stir processing (MFSP) technique in producing aluminium-based surface composites. It further looks at the progress made in using the MFSP on aluminium-based welded joints. An effort is made to identify the gap that requires some exploration for the better utilization and understanding of this technique
