Abstract: Provided is a TRIP-aided dual-phase martensitic steel which is excellent in terms of strength-elongation balance and Charpy impact value and has dual-phase martensite composed of a soft lath martensitic structure and a hard lath martensitic structure as a matrix phase, regardless of forging temperature or forging reduction ratio, by controlling heat treatment conditions. The dual-phase martensitic steel contains 0.1-0.7%C, 0.5-2.5%Si, 0.5-3.0%Mn, 0.5-2.0%Cr, 0.5% or less (including 0%) of Mo, 0.04-2.5%Al, and the balance Fe with incidental impurities; has its metallographic structure in which a matrix phase is composed of a soft lath martensitic structure and a hard lath martensitic structure; and obtained by heating its raw steel material to a ³-range, rapidly cooling the heated material to a temperature slightly above a martensite transformation starting temperature (Ms), and then performing an isothermal transformation process the cooled material in the temperature range from Mf to [(Mf)-100°C].

Abstract: A stopper (32) includes one end-side side wall (33) confronting one end surface of a control shaft side link pin irrespective of a rotation positon of the control shaft; the other end-side side wall (34) confronting the other end surface of the control shaft side link pin irrespective of the rotation position of the control shaft; one end side flange (36) fixed to an upper oil pan (23); and the other end side flange (37) fixed to the upper oil pan (23). With this, the end surface of the control shaft side link pin is partially overlapped with the one end-side side wall (33) and the other end-side side wall (34) of the stopper (32) when viewed in an axial direction of the control shaft side link pin, irrespective of the rotation position of the control shaft. Accordingly, it is possible to surely prevent the control shaft side link pin from falling off in the axial direction of the control shaft side link pin, irrespective of the rotation position of the control shaft.

Abstract: There is provided a production method for a titanium-alloy connecting rod that ensures high rigidity of a cutting tool. One embodiment of the present invention provides a production method for a titanium-alloy connecting rod (1) in which a rod portion (33) and a cap portion (34) of a big end (30) are fixed by using a bolt (40). The production method for the titanium-alloy connecting rod (1) includes a step of forming a bolt hole (32) for the bolt (40) to extend therethrough. The step of forming the bolt hole (32) includes: forming a first hole (61) in the cap portion (34) and the rod portion (33) in a direction from the cap portion (34) toward the rod portion (33); and forming a second hole (62) in the rod portion (33) in a direction from the rod portion (33) toward the cap portion (34). Once the first and second holes are formed, the first hole (61) and the second hole (62) communicate with each other. The longitudinal direction (LD2) of a cutting tool (52) used for forming the second hole (62) is inclined with respect to the longitudinal direction (y) of the rod main body (10) of the titanium-alloy connecting rod (1).

Abstract: The present disclosure relates to a connecting rod (14). The connecting rod (14) may comprise a small end (32) including a bore (34) for receiving a piston pin (16). The bore (34) may have an inner face (38) with a shank sided section (48) and a piston crown sided section (50). The inner face (38) at the shank sided section (48) may delimit a piston pin supporting structure (36) that provides less material next to a first lateral face (40) and a second lateral face (42), respectively, in a shank direction (E) than at an azimuthal side position (F) at about 45° relative to the shank direction (E).
