One of the early studies concerning the detailed microstructural aspects of phase transformations in iron-carbon alloys was performed by Chih-Hung Chou (Ph.D., Harvard, 1928), a student of Professor Albert Sauveur. The research describes the formation of Widmanstatten structure and martensite in iron-carbon alloys possessing a broad range of carbon contents and heat treated using a broad range of cooling rates. A unique mercury quench method is described. This research work was never fully published.
The present paper shows original photomicrographs and portions of the written text from the dissertation, and seeks to clarify and reinterpret these in terms of our present understanding of ferrous phase transformations. Also included is the background history of the introduction of modern industry and science in China, and Chou's personal reminiscences of Professor Sauveur.

Definitions. For purposes of this License, an Authorized Site is a localized site (one geographical location) that is under a single administration at a single location. For a Subscriber with locations in more than one city, each city is considered to be a different site. For a Subscriber with multiple locations in the same city, each location is considered to be a different site. (If you are seeking online access for multiple sites, please contact Kathe Hooper, ASTM International, at firstname.lastname@example.org or phone: 610-832-9634). Authorized User means only the employees, faculty, staff, and students officially affiliated with the Subscriber at the Authorized Site, and persons with legal access to the library's collections and facilities at the Authorized Site, using an IP address within the range identified in the subscription. Authorized Users may be persons remote from the Subscriber's physical location whose access is administered from the Authorized Site, but not persons at remote sites or campuses with separate administrations. For example, an employee of the Subscriber may be considered to be an Authorized User when accessing the Subscriber's network from home or while traveling to another city; however, employees of a branch campus or facility in another city are not considered to be Authorized Users. Subscriber is the person or entity which has subscribed to the ASTM journal and agreed to the terms of this limited license.
