Foundation of bulk amorphous alloy database

During the past 10 years, research about bulk amorphous alloys has made some progress and a great quantity of data has been published. One of the main studying aims is to find a series of alloys with high glass-forming ability so they can be fabricated by conventional casting or high-pressure die casting techniques. However, traditional “trial and error’’ methods have still been used to explore new bulk amorphous alloy systems. It is time to design bulk amorphous alloy compositions by computer aided design referring to condensed state physics, computational materials science and database. A database has been assembled with a lot of documents and data about bulk amorphous alloys. It has convenient inquiry, index, and modification functions. In the database, disorder data have been systemized and regularized, and can be directly used by other computational programs. It concluded that the bulk amorphous alloys database is especially helpful to research and design bulk amorphous alloys.     

Werkstoff-Datenbank

Material database This paper describes a new materials database named SWDB. SWDB is the German abbreviation for „Sollwert-Werkstoff-Datenbank”︁ and should be read as „Specified-Materials-Database”︁. SWDB is a state of the art user friendly materials database which provides adequate information on standardized and not standardized materials characteristics of solid materials from ferrous and non-ferrous metals and other metallic alloys currently used in engineering practice. Apart from the chemical composition and mechanical-technological properties of metallic materials based on various standards and specifications, the database includes reference to a large number of possible alternative materials in a concise and pregnant form which is transparent and easily accessible for application engineers. The material data are composed on the basis of an absolutely new structured model and are shown as a function of the specified material, product shape, dimension, delivery condition and sampling. SWDB includes additional information on physical properties as well as exhaustive information on heat treatment, hot and cold forming, weldability and hints for application. The SWDB has a dual character: on the one hand it can be operated as an individual and independent database, on the other hand as a satellite database to support the corrosion database within the information system on corrosion and protection, „CORIS”︁.     

Functional model for the development of an inspection integration framework

Product dimensional inspection is set as one of the essential parts of the production process, where not only product quality test is checked but also its interaction with other development stages in a minimal time. This enables a feedback to make quicker production and design decisions, provides updated information about the inspection processes to be shared and used in the new development processes, and permits the simultaneous work in the preparation of the inspection processes themselves. For this aim, it is necessary, as it occurs in the STEP framework, to develop an application context that includes all dimensional inspection aspects, from the geometrical and measurement aspects to those related to administration and configuration product data. This paper proposes a solution to integrate the dimensional inspection process with coordinate measuring machines with the design and manufacturing processes. Integration is achieved through a common product information model. A functional information model, a reference information model and an interpreted information model have been defined. The interaction with other information models associated to other activities of the production cycle is possible. Tests have been made of the possibility of making the inspection information interchange at the operation level instead of making it at the CMM trajectory level, as it is the case of the current DMIS format. This level of information definition is easier to put into effect, easier to interpret, and it is more productive.

In order to test the validity of the information model, a real work environment which has been called IFCIA (Inspection Framework for Concurrent Information Access) has been developed. The IFCIA architecture is composed of a product modelling system, an object-oriented central database and a tri-dimensional coordinate measuring machine. The model has been implemented on an object-oriented product central database which is accessible by all the applications, so that the access to data is achieved in a concurrent way and in real time for the different agents involved in the development cycle, in a heterogeneous framework of platforms and applications. The generation and transference of the information among these systems are carried out exclusively according to data structures defined in the information model.
