چکیده مقاله:

Polymer-based nanocomposites due to their advantages such as corrosion resistance,adequate mechanical properties and low cost are widely used in modern technologies. The increasing application of these nanocomposites, and hence their welding seems unavoidable. In this paper, a novel hottool in friction stir welding process is used for butt welding nanocomposite plates of 5 mm thick containing polypropylene , ethylene-propylene diene monomerand Cloisite 15A. Response surface method is used to design experiments and determine the effect of process parameters such as tool rotational speed, welding speed, tool shoulder temperature and clay content on weld tensile strength. The results show that although increasing clay content in the base material increases its tensile strength but decreases the weld tensile strength; such that in the specimens with 0, 3 and 6% clay content, the weld tensile strength equals to 94, 80 and 61 percent of the respective base materials.

The Strength of Friction Stir Welded and Friction Stir Processed Aluminium Alloys

Local strength of friction stir (FS) welds and FS processed aluminium alloys in heat treatable aluminium alloys is dominated by precipitation hardening. Strengthening due to stored dislocations is generally limited to 40MPa, and grain size strengthening is generally less than 10MPa. Local crystallographic texture can cause yield strength variation on the order of 5%. Published models for streng...
