Abstract:

Inverse analysis of nanoindentation data has attracted increasing interest in industry due to its ability to estimate the bulk tensile properties of materials and potentially offers an alternative technique to conventional characterisation methods. Inverse analysis of nanoindentation data is particularly valuable in applications where conventional techniques are not suitable due to either the scale of characterisation (very small regions) or because the testing is expensive and time consuming. Despite using best practices to minimise sources of error in the experimental data, given the scale o

Microstructure and photonic crystal fibers with periodic as well as random refractive-index distributions are investigated. Two cases corresponding to fibers with one-dimensional (1D) radial index distributions and two-dimensional (2D) transverse index distributions are considered. For 1D geometries with an arbitrary number of cladding layers, exact analytical solutions of guided modes are obtained using a matrix approach. In this part, for random index distributions, the average transmission properties are calculated and the influence of glass/air ratio on these properties is assessed. Import

This work explores the processing-microstructure-property relationships in two-phase titanium alloys such as Ti-6Al-4V and Ti-5Al-5V-5Mo-3Cr that are used for aerospace applications. For this purpose, an Integrated Computational Materials Engineering approach is used. Microstructure and texture of titanium alloys are characterized using optical microscopy, electron backscatter diffraction and x-ray diffraction. To model their properties, threedimensional synthetic digital microstructures are generated based on experimental characterization data. An open source software package, DREAM.3D, is us

Abstract:

Light vehicle engine pistons have traditionally been cast from near eutectic Al-Si cast alloys due to several favourable functional and processing attributes. The increasingly demanding engine performance requirements have necessitated the need for the development of multicomponent alloys with high alloy content and highly complex microstructure. In this regard, recent trends in new piston alloy development have been to increase the level of various alloying elements such as Cu, Ni and even Si. However, low Si compositions of ∼7 wt% Si and ∼0.7 wt% Si have also been proposed largely due to obs

I investigate the trading decisions of a large institutional liquidity trader by using a detailed data set from a transition management firm. The data set contains records for all trades of transitions completed between January 2008 and September 2008. Effective execution involves a trade off between trading patiently over time to minimize price impact costs and trading quickly to avoid opportunity costs due to price volatility. I estimate a model of transition duration that accounts for volatility, an order's percentage of average daily volume, and the bid--ask spread to uncover the firm's s

Abstract:

Block copolymers have attracted interests for potential application ranging from dynamic photonic sensors to solid-state ion conductors. However, due to nucleation and growth mechanism, block copolymer inherently forms granular microstructure with defects such as grain boundaries. Understanding the microstructure of block copolymer is thus crucial in many applications because the microstructure determines the transport property of functional fillers such as ions in block copolymer template. Previous research has shown that athermal filler segregated to grain boundary of lamellae block copolyme

In the process of developing cast iron and cast aluminium components, the co-operation between product development and production is important. On the engineering level, this co-operation is limited already in the product development phase e.g. by the lack of established methods to consider the mechanical behaviour of the completed component. This thesis aims to increase the possibilities for co-operation in the product realisation process between product development and production by enabling the use of predicted local mechanical behaviour in structural analyses of cast components.

The mechanical performance evaluation of asphalt binder has always been a challenging issue for pavement engineers. Recently, the Phase Field Method (PFM) has emerged as a powerful computational tool to simulate the microstructure evolution of asphalt binder. PFM analyzes the structure from the free energy aspect and can provide a view of the whole microstructure evolution process. In this dissertation, asphalt binder performance is analyzed by PFM in three aspects: first, the relationship between asphalt chemistry and performance is investigated.

Rare earth magnet materials are commonly used in many applications, such as the motors in hybrid and electric vehicles.

In this context, more research is being conducted to develop of free rare earth magnets that combine high coercivity and high thermal resistance.

Accurate predictions of the microstructure evolution of thennomechanically processed metals and alloys are generally only achieved when the defonnation process is nominally linear.

碩士<br>國立臺灣海洋大學<br>機械與機電工程學系<br>95<br>Analysis of fatigue behavior of titanium alloys Ti64 (Ti-6Al-4V) and SP700 (Ti-4.5Al-3V-2Mo-2Fe) were performed to examine the trend of cyclic hardening or softening, hysteresis loops, and fatigue life. The cyclic stress-strain curves of Ti64 and SP700 alloy exhibit material softening behavior, being independent of strain rate. The plastic fatigue life of SP700 is superior to that of Ti64 alloy at low strain rate of 10-4 S-1. The long patches twins occur at low strain rate in α phase is profitable to extend fatigue life than short segment twin at high strai
