1. A method of forming a golf club head assembly, the method comprising:
(a) providing an ingot formed from an α-β titanium alloy, the α-β titanium alloy comprising between 5.0 wt % and 7.0 wt % aluminum (Al), between 1.0 wt % and 5.5 wt % Vanadium (V), between 0.75 wt % and 2.5 wt % molybdenum (Mo), and a Ti balance,
(b) radial forging the ingot to form a billet;
(c) slicing the billet to form a section;
(d) press forging the section to form a plate;
(e) cross rolling the plate to form a sheet;
wherein the plate is heated to a temperature between 850° C. and 950° C. prior to cross rolling;
(f) laser-cutting the sheet to form a desired shape of a faceplate of the golf club head assembly;
(g) aligning the faceplate with a recess of a club head of the golf club head assembly;
(h) welding the faceplate to the club head;
(i) heating the club head and an entirety of the faceplate to a temperature lower than a solvus temperature of the faceplate for a predetermined amount of time;
wherein the solvus temperature is between 800° C. and 1000° C.:
(j) cooling the club head and the faceplate by an inert gas;
(k) heating the club head and the faceplate to a temperature between 500° C. and 700° C. for a predetermined amount of time; and
(l) cooling the club head and faceplate by an inert gas and by air.
