Abstract: Described herein are embodiments of an iron-type golf club head comprising a rear opening and an insert. The insert either partially or fully occupies the club head interior cavity. The insert damps vibrations occurring within the club head at impact to provide a desirable sound and feel. The insert is formed of a low-density material, thereby providing a significant damping effect while also creating discretionary mass.

Abstract: Embodiments of golf club head faceplates comprising a lattice to improve the energy storage capabilities and minimize stress concentrations are described herein. The lattice can comprise a plurality of flexure shapes that facilitate in faceplate bending. The flexure shapes of the lattice can comprise a reentrant, concave, or non-convex shape. The lattice can comprise at least one repeating pattern of flexure shapes that can be interconnected or spaced apart. During golf ball impacts, the flexure shapes flex to store energy through linear and torsional bending.

Abstract: A method of forming a golf club head assembly includes aligning a faceplate with a recess of a club head; welding the faceplate to the club head; then, after welding the faceplate, heating the club head and the faceplate to at least a solvus temperature of the faceplate for a predetermined amount of time; and then, after heating the club head and the faceplate, allowing the club head and the faceplate to air cool.

Abstract: An iron-type golf club head with a cavity formed via a multi-stage forging process. The forged iron-type golf club head is formed from a single billet of material. An intermediate step of the multi-stage forging process creates a cavity in the iron-type golf club head which can receive an insert. The resultant iron-type golf club head has a substantially lower center of gravity and higher moment of inertia when compared to a traditionally forged iron-type golf club head lacking a cavity. Additionally, the resultant iron-type golf club head has a more solid feel than a traditionally cast iron-type golf club head as a result of the tighter grain structure the forging process yields.

Abstract: A wood-style golf club head includes a strike face and a body that cooperate to define a hollow internal club head volume. The strike face formed from a strike plate having an outer perimeter and a frame surrounding the strike plate. The strike plate is affixed to the frame across the entire outer perimeter. The strike plate and frame define a continuous ball striking surface that has a surface texture characteristic of milling that extends continuously across both the strike plate and the frame.

Abstract: A golf club head having localized heat treatment is described herein. Other embodiments are disclosed.

Abstract: A method of manufacturing a forged iron type golf club head with a cavity. The method of manufacturing comprises forming a billet into an intermediate club head body with a strike face comprising an upper region and a lower region; hot pressing a cavity into the rear portion of the intermediate body; and bending the strike face of the intermediate club head body to form a golf club head with a cavity and a planar strike face. Other embodiments are disclosed.

Abstract: A golf club head includes a crown surface having an apex at a highest point and extending between the face, the rear, the heel and the toe of the golf club head. The golf club head also includes a plurality of crown turbulators projecting from the surface of the crown and located between the face and the apex, wherein each adjacent pair of crown turbulators is separate and spaced apart to define a space between the adjacent pair of crown turbulators.
