A method for producing a carbonitrided member comprising the steps of carburizing a steel part having a composition of, by mass percent, C: 0.10 to 0.35%, Si: 0.15 to 1.0%, Mn: 0.30 to 1.0%, Cr: 0.40 to 2.0%, S: 0.05% or less with the balance being Fe and impurities in a carburizing atmosphere of 900 to 950&#xb0; C. The carburized steel part is carbonitrided in a carbonitriding atmosphere with the temperature of 800 to 900&#xb0; C. and the nitrogen potential of 0.2 to 0.6%. The carbonitrided steel part is qhenched and then shot peened. The shot peening treatment may be further performed while heating to a temperature not higher than 350&#xb0; C. or immediately after heating to a temperature not higher than 350&#xb0; C. After quenching, the shot peening treatment may be further performed after tempering in the temperature range exceeding 250&#xb0; C. and not higher than 350&#xb0; C.

A method of forming a powder metal fractured bearing component, such as a connecting rod, includes the step of forming a component blank having a bearing aperture for separation of the component blank into a main body and a bearing cap, wherein the component has a hardness in the range of about HRC 22 to about HRC 34. The method also includes the steps of forming a stress riser in the blank where the fracture is to occur, and fracturing the component blank of the connecting rod into a main body and a bearing cap by applying tensile force thereto, in order to form a surface area ratio of &#x3e;113% on the mating surfaces of the main body and the bearing cap.

A racemic alcohol is subjected to the optical resolution by irreversibly esterifying one of the two antipodes of the racemic alcohol with an acid anhydride or enol ester of a carboxylic acid in a organic solvent in the presence of a hydrolase. This optical resolution uses a non-aqueous organic solvent in which the hydrolase is insoluble and involves an irreversible esterification, thus permitting an efficient optical resolution and improving recovery and re-usability of the hydrolase.
