The first natural occurrence of SR-TRM was discovered by Nagata et al. (1952) in samples from the Haruna dacite and later shown to be carried by intermediate members of the ilmenite-hematite solid solution (Uyeda 1955). Since then there have been many attempts to determine the origin of the self-reversal effect (Uyeda 1957, 1958 Ishikawa 1958, Ishikawa and Syono 1963, Hoffman 1975, 1992 Varea and Robledo 1987, Nord and Lawson 1989, 1992 Hoffmann and Fehr 1996, Bina et al. 1999). Many of the early attempts to interpret experimental observations on self-reversing material were hampered by the lack of information about the equilibrium phase diagram. It is useful, therefore, to reappraise this work in light of recent experimental and theoretical studies which provide stricter constraints on the phase transformation behaviour in this system (Burton 1984, 1985, Ghiorso 1997, Harrison et al. 2000a,b). 

Finally, organic additives can affect the thermal properties (phase transformation behaviour) of mesoporous ceramic membranes. Ziiter [15] reported the transformation from monoclinic to tetragonal particles and back as a function of the amount of PVA.

For steels not listed individually it is advisable to consult TWl to determine whether new information on weldability has become available. If much welding of an unlisted steel is envisaged, some experimental work to determine its transformation behaviour and susceptibility to cracking is recommended. The cost of this in most cases will be more than offset by savings either in unnecessary preheat or in repair. 

As a first step the steel is placed in one of five grades by means of Table 4.3. These grades are based on welding tests, on studies of the continuous cooling transformation behaviour of steels, and on an empirical formula relating composition to maximum HAZ hardness ... 

In the description of the principle of this method in Chapter 2 it was explained that a knowledge of the transformation behaviour of a steel made it possible to control the cooling of the weld HAZ and so to produce certain preferred, i.e. less crack sensitive, microstructures. To use this technique it is necessary to know the isothermal transformation characteristics of the steel. These may be obtained from the steel-makers data sheets or from one of the collections of such data. As explained in Chapter 2, a temperature is selected... 

Since our pioneering study on as-received [22] nickel-titanium endodontic instruments, other DSC studies have confirmed that as-received instruments are in the superelastic condition, which persists after numerous sterilization cycles [28,29]. As would be expected, mechanical properties of these instruments are related to the phase transformation behaviour of the nickel-titanium alloy [30]. Accordingly, suitable elevated-temperature heat treatment may favourably alter the mechanical properties of these instruments [31,32], as was previously found for nickel-titanium orthodontic wires [21,33]. 

Our research group performed a DSC study [25] to investigate the differences in phase transformation behaviour for two superelastic, one non-superelastic and...

Using equations (2.6) and (2.7), all strains can be calculated if they are assumed to be small. However, they cannot be used as components of a tensor, for they do not transform correctly as tensors should. A correct transformation behaviour can be achieved when the shear strain 7 is replaced by half of its value Sij = 7ij/2. An additional advantage of this formulation is that equations (2.6) and (2.7) do not have to be written separately for the components, but can be collected in one equation ... 

The transformation behaviour of plastic mold steels are described in time, temperature, transformation (TTT) curves in order to better understand the transformation processes involved in hardening and in austenitizing. 

For hardening and subsequent tempering operations, the heat treatment contractor should be guided by the recommendations of the steel maker given in the data sheets for the material concerned. These heat treatment recommendations are derived from the chemical composition of the steel used. Material-specific, continuous and isothermal Time-Temperature-Transformation (TTT) diagrams, as shown in Figure 4.80, describe the transformation behaviour of the steel s microstructure [3]. 

Failure responses of a component to its input can be expressed in a simple language based on patterns. For example, the following expressions denote examples of failure propagation and transformation behaviours for a trivial single-input single-output component an omission fault at the input may propagate through the component, but a late fault is transformed to a value fault at the output. 

Connectors in an architectural model of a system are the links between components. In FPTA, we provide a different semantics to connectors than in FPTC they are an abstraction that does not have any failure transformation behaviour. Specifically, they propagate whatever they receive from an input port to an output port. Thus, failure behaviour is modelled exclusively on components this, as we will see, simplifies the probability calculations.
